Maintenance and Servicing
8.1.4 Cooling compressor
In order to guarantee perfect
function and long lifetime of the
refrigeration unit, it is absolutely
essential to remove dust deposits
from the condenser ( Fig. 33 , no. 1)
(with a vacuum cleaner, paintbrush
or bottle brush, depending on the
amount).
After the screws (2) have been
loosened, the air inlet cover on the
front (3) can be removed and the
condenser can be cleaned.
After the screws have been loos-
ened, the air inlet cover on the
rear (4) can be removed as well,
to clean the refrigeration module
from both sides if necessary.
